Required grain frequency (grains/s)
too high Reduce working speed.

Check lines and connections for
leaks.
Grain feed gate set incorrectly Set the grain feed gate correctly. Ad-
justments in both directions may pro-
duce improvements.

(greater number).
• Set the gate valve down (smaller

Separating units and metering discs
soiled by deposits (dressing, dust) Clean dirty parts.
